Abstract
with the development of computer hardware and software performance improvement, digital multimedia technology has been applied to various fields, the effect of image visional transmission are mainly affected by the brightness, texture and color, and different image effects will produce different visual transmission effect. This paper starts from the brightness of the image, using the mathematical model of digital multimedia brightness change, and combined with MATLAB numerical simulation software, the digital multimedia visual effect design interface is developed. In order to verify the reliability of the design of digital multimedia solutions, image has been brightness correction in the digital multimedia visual effect interface, and then by changing the environment light, diffuse reflection and specular reflection light, we can change the effect of image digital communication. Finally, we will obtain better visual communication effect, to provide a theoretical reference for the development of digital multimedia technology.
